What is voter fraud?

The relatively straight-forward question seems to be alluding lots or reporters this week. Especially ones employed by Rupert Murdoch.

In a lengthy media analysis, the Brad Blog looks at how conservatives online are whipping themselves into a frenzy over a story that may be less than what it appears:

Those who wish to believe in the hoax, however, attempt to link to article after article about allegations of voter fraud carried out by ACORN. And yet, the articles themselves

if one bothers to actually read them reveal that either 1) They describe allegations and investigations brought by Republican agents, with little or no evidence of any wrong doing, and certainly no "voter fraud" 2) Where voter registration fraud has occurred it has been by rogue ACORN employees, originally reported to authorities by ACORN themselves (who are the actual victims of any such fraud by their employees), or 3) Smoke and mirrors are used to cloud the fact that not a single fraudulent vote has actually been cast by anyone.
